[asterisk-dev] Extend MixMonitor to record stereo files

[Alex Barnes]

Hi all,

I was hoping somebody knowledgeable about the inner workings of app_mixmonitor could give me an idea of how feasible our change might be?

User Story:
As a FreePBX user I would like MixMonitor to save recordings in stereo wav format where inbound calls are one channel and outbound are another.
This will allow me to more clearly hear who is speaking as well as more easily extract the audio of just one speaker.

Note:
The "FreePBX" part is important as we cannot make it use Monitor and an external bash script without hacking apart a lot of the dial plan, hence we are stuck using MixMonitor.

We are a dev company but with little C experience and zero Asterisk application development knowledge HOWEVER we're very happy to give it a whirl.

I'm literally just starting on researching this and no doubt have lots of reading to do regarding general Asterisk app development, research WAV format issues in C and MixMonitor, how to submit changes to the Asterisk project etc etc.  I was hoping somebody could let me know if they think this will definitely not work or if they happen to know of some of the issues we may face and possibly where to start looking.

Thanks in advance

Alex
